Undercover by Orbicule is not new, but version 3, just released, adds Skyhook Wireless integration, the same technology that powers location tracking on the iPhone and the iPod Touch.

Skyhook allows much more precise location details, now 30-60 feet. And Orbicule's recovery center can handle everything with this technology, whereas in the past some cooperation with the ISP was necessary.

As with earlier versions, their iSight pictures provide you with a picture of whoever is using the notebook from the camera on the MacBook. Undercover also takes screen shots so you know what the current user is doing with the computer.

Orbicule claims an 86% recovery rate with their old versions. This number should go up with version 3. A single user license is $49, a household license $59, and a student license $39.
